To all whom it may concern:

Be it known that I, Hi'PPoLY'r SAURER, a citizen of the Republic of Sw1tzerland, re

siding atArbon, Switzerland, haveinvented new and useful Improvements 1n Auto-mane This invention relates to improvements automatic emb'roidering machines and 'consists in a device for converting a motionbf rotation ofia certain valuefinto a variable rectilinear motion for impellii'ig the frame. Forn'iovi-ng the frame in "anyi di'rection" a plane two components are necessary which are independent of each other and adapted to attain positive and negative. values.

According tof'this invention theconstant motion of rotation of a shaft which revolves in invariable direction, is converted into a variable positive and negative mo: tion. For this purpose thefishaft is com: posed of at least. two parts, the parts being connected to each other by a reversing gear so that the two parts revolve inxcontrary direction. g Motions of different direction jbecome available hereby on the partsof the shaft.

I n the accompanying drawings- Figurelv shows a vertical section'of said device' Fig. 2 is a plan view of the same, the shafts being shown as transferred into the same horizontal plane, Fig. 3 shows the device in connection with an embroidering machine.

To the shaft A is imparted a periodical motion of rotation of a certain value by means of a suitable-cam mechanism 40 and a ratchet 4:1. The shaft A is composed of two parts 1 and 2, which are connected to each other by a reversing gear 5 causing the two parts 1 and 2 to rotate at the same speed but in contrary directions. To the part 1 are secured toothed wheels 6, 7 and S of different diameters. To the part 2 are also secured toothed wheels 9, 10 and .11 of different diameters. The wheels 6 and S), as well as 7 and 10, and 8 and 11 are always of the same diameter. The shafts 12 and 13 are mounted parallel to the shaft A and carry each by slot and key, but mov- Specification of Letters Patent. Patentgd Sept, 28 1915 Application filed June 19, 1911.

ably in axial direction a couple of toothed wheels19 and-20 of different diameters with a sleeve 18, a couple of toothed wheels 22 and 23 of the same diameter with a sleeve 21. and a couple of toothed wheels 25 and 26 of difiere'nt, diameters with a sleeve 24.

The wheels 20 are of the same size asthe wheels 25'a11d the wheels. 19 are of the same size as the wheels/26'." A toothed wheel 27 issecuredfto the shaft 13 and engages a wheel 36 of'smalle'r diameter mounted on the shaft 12. The motion of the shaft 13 is transmitted as one'component to the pin of thepantographet bvmeans of a differential' gear a2, bevelwheels e3 anda chain and chainwheel,mechanism ,For forming the second component two more shafts 15 and 16 (Fig. 1) are arranged parallelto' the'shaftA. These two shafts FED STATES rnriin'r orr cn.

areomitted in Fig. 2, since they are of'the same form and en-mare same wheels as theshafts 12 and 13. The shaft" 15 is con nectedto the pantograph in the same manner as the shaft 13. If, for instance by shifting the wheels 19, .of the shafts '13, or

12 toengage wheel 6 a motion is to be. obtained which is of the same value but of the contrary direction as when the wheels 26 and 9 engage each other. The wheels 6 and 19, and 9 and 2 6of the" shaft 12 are of the sameratio of gearing, excepting that a further ratio of gearing is introduced in this .case bythe wheels 36 and 27. .Other variations" can be'obtained by the wheels 2.0,an'd7, 25 and 10, 22*and 8 and.23 and ,11. i L The displacement of the wheels 19,-26 is positively and automatically effected by the Jacquard apparatus 50 whichby suitable means actuates the sleeves 18,21 and 24.

The shaft A can be composed of more than two parts, as four parts for instance.

I claim:

1. In mechanism for transmitting move ments to the embroidery frame of embroidering machines; the combination which comprises an actuating shaft composed of alined sections and reversing mechanism be tween them, means for imparting movement to said shaft, and only two parallel shafts driven from said shaft for imparting movement to theembroidery frame for one of its components of movement, the movements imparted to the. actuating shaft being in the same direction and throughv the same angle.

2. In mechanism for transmitting movements tothe embroidery frame of an em- .broidering machine, the combination which comprises an actuating shaft composed of two al ned sections and reversing mechanism between them, whereby said sections have equal and opposlte rotation, means for imparting rotation to one of the sectlons,

and only two parallel shafts driven from said shaft for imparting movement to the embroidery frame for one of its compobroidering machine, the combination which" comprises an actuating shaft composed of two alined sections and reversing mechanism between themrwhereby said sections have equal and opposite rotation, cam-actu- I ated'pawl and ratchet mechanism for. im-

l parting a step by step rotation to one of the sections, and only two parallel shafts'driven from said shaft for imparting movement to the embroidery frame for one of its compo-' nents of 1novement,the movements imparted to the actuating shaft being in the same .di-.

rectionand through the same angle. 7 1

4. In combinatlon, an actuating shaft'con sisting of a plurality of alined sections, .re,. 'verslng. mechanism between ad acent sections, diiferentsized gear wheels secured on each section, only two shafts for each component of movement parallel to the actuat ing shaft, 'gearwheels' slidable but not rotatable relatively to said shafts'arranged to selectively gear with the gear wheels on the sections, difl erential mechanism between the parallel shafts, a vmember from which the embroidery frame is moved and rotated by the last named difli'erential'mechanism, and means to actuate one ofthe sections.

5. In combination, an actuating shaft (Copies of this patent may be obtained for five cents each, by addressing the Commissioner of iatents,

consisting" of" alined section's, reversin mechanism between the sections, different I sized gear wheels secured on each section,

only two shafts for each component of movement parallel to the actuating shaft, gear wheels slidable but not rotatable relatively to said two shafts and arranged to selectively gear with the gear wheels on the sections, 1

differential mechanism between the parallel shafts, a member rotated by the last named differential mechanism from which the embroidery frame is actuated andmeans for actuating one of said sections step-by-step.

6. In mechanism for transmitting move- ,ments to the embroidery frame of embroiderlng machines, the 'comblnation whlch com- :shaftsfor imparting movement to the embroidery frame for one of its components of movement, a second set of'like parallel shafts, gear wheels thereon,and adding mechanism for imparting movement to the embroidery, frame for its other component of movement, and means for lmpartmg a stepby-step rotation to one of said sections in one direction and through equal angular steps.
